Background: Fibromyalgia syndrome (FMS) is a chronic disorder characterized by widespread musculoskeletal pain accompanied by various additional symptoms. The prevalence of FMS ranges between 2–8% of the population. The exact pathophysiology of the disease remains unknown, and under certain circumstances it is difficult for the physician to diagnose. Previous studies have shown a correlation between inflammatory biomarkers such as C-reactive protein (CRP) and FMS activity, suggesting that an inflammatory component may play a role in this disease pathogenesis.

Objectives: To investigate the role of certain new inflammatory biomarkers in the diagnosis of patients with FMS.

Methods: In this study data were collected from FMS patients who were admitted to Ziv Medical Center during the period 2013 to 2019 in an attempt to find a connection between inflammatory markers detectable by a traditional complete blood count (CBC) tests such as neutrophil-lymphocytes ratio (NLR), platelet-lymphocyte ratio (PLR), mean platelet value (MPV), red cell distribution width (RDW), and C-reactive protein (CRP) and FMS.

Results: We found significantly higher CRP levels, MPV, and PLR and lower lymphocyte count in the FMS group compared to the control group.

Conclusions: FMS has certain inflammatory components that may be useful in disease diagnosis

Background: Cardiac resynchronization therapy (CRT) is a non-pharmacological option for patients with heart failure and interventricular dyssynchrony. Elevated red cell distribution width (RDW) reflects higher size and heterogeneity of erythrocytes and is associated with poor outcome in patients with chronic heart failure. 

Objectives: To examine the association between RDW levels and outcomes after CRT implantation.

Methods: We conducted a cohort analysis of 156 patients (126 men, median age 69.0 years) who underwent CRT implantation in our institution during 2004–2008. RDW was measured at three time points before and after implantation. Primary outcome was defined as all-cause mortality, and secondary outcome as hospital re-admissions. We investigated the association between RDW levels and primary outcome during a median follow-up of 61 months.

Results: Ninety-five patients (60.9%) died during follow-up. Higher baseline RDW levels were associated with all-cause mortality (unadjusted HR 1.35, 95%CI 1.20–1.52, P < 0.001). On multivariate analysis adjusted for clinical, electrocardiographic and laboratory variables, baseline RDW levels were associated with mortality (HR 1.33, 95%CI 1.16–1.53). RDW levels 6 months and 12 months post-implantation were also associated with mortality (HR 1.22, 95%CI 1.08–1.38, P = 0.001; and HR 1.15, 95%CI 1.01–1.32, P = 0.02, respectively). Patients who were re-admitted to hospital during follow-up (n=78) had higher baseline RDW levels as compared to those who were not (14.9%, IQR 14.0, 16.0% vs. 14.3%, IQR 13.7, 15.0%, respectively, P = 0.03). 

Conclusion: An elevated RDW level before and after CRT implantation is independently associated with all-cause mortality.
